The crankshaft hole honing special machine tool is developed by Yinchuan Dahe CNC Machine Tool Co., Ltd. through continuous innovation, based on market and customer needs, relying on the professional technical research and development of the National Engineering Laboratory and Academician Workstation for engine crankshaft hole honing. It is suitable for the honing and grinding of automobile engine crankshaft holes.

For the two types of cylinder bodies that need to be processed, it is only necessary to replace the height of the honing tool and workpiece positioning pad while keeping the main structure of the machine tool unchanged. The crankshaft hole honing machine adopts a horizontal structure, and the spindle box is a gear reducer. The rotation speed of the honing cutter is controlled by a spindle servo motor, and the feed speed and position of the tool are controlled by a CNC slide table. The CNC system of the machine tool adopts Guangzhou CNC CNG980HC system. The loading and unloading of machine tool fixtures can be done by robots or material lines. The fixtures are positioned with one side and two pins, and the flat surface of the cylinder body is clamped by hydraulic pressure.

Main components of the machine tool: spindle rotation mechanism, spindle reciprocating mechanism, tool guide bar expansion mechanism, hydraulic system, lubrication system, bed body, cooling system, fixture, electrical system, honing tool, etc.
